It holds 67 gallons in the test, 1 gallon more than its 66-gallon sold size. It delivers 79 gallons of hot water in the test's first hour. That is 12 gallons more than its tank holds, since it reheats during the hour. Among 481 heat pump models, 165 have a higher first-hour rating. The median heat pump model gives 72 gallons in its first hour.

Its single model number, HPHE6266H045DV 1**, is ENERGY STAR certified. In the test, it gives 3.42 units of hot water energy per unit it uses (its UEF). Pulling heat from the air lets its UEF pass 1. Its test simulated a day of high hot water use (its draw pattern). Its UEF is lower than that of 216 of the 237 heat pump models with its draw pattern. A UEF of 3.88 is the median for its type and draw pattern. Its recovery efficiency is 265%, because it takes heat from the air as it reheats water.
